Yes, Doug. This is Gary. Certainly, getting total light product inventory, we built a significant surplus, especially early on in the pandemic. So, seeing that surplus essentially gone and getting back into the five-year average range is very encouraging. As you know, as demand starts to pick up, it will allow margins to recover much quicker. I think, encouraging -- another encouraging sign is the fact, despite the fact that we've had a surge in COVID cases, gasoline demand for the DOE is still a little bit above 90% year-over-year where it was last year at this time. Our wholesale volumes are showing to be pretty close to that. And so, the combination of reasonable gasoline demand and relatively low gasoline inventories has caused the prop market to be a little stronger. I think, one of the key things there is the stronger prop market has really flattened the curve on gasoline. And so, it's taking away a lot of that incentive to store summer grade gasoline, and that certainly sets up for a stronger driving season in terms of gasoline margins. As Joe said, I think, we view that we'll see gradual recovery. Second quarter, you'll start to see things pick up. And then we expect things to be fairly normal by the third quarter, with the exception that we do see that there could be a lot of pent-up demand, and people that are spending disposable income largely buying things that they're ordering are going to spend that disposable income getting out and on experiences, family vacations, which could cause a surge in gasoline demand. On the diesel side, as you kind of mentioned, diesel demand is really hung in there pretty strong. So, DOEs are showing over 98% year-over-year diesel demand. Actually, at the seven-day average in our system, we were at 111% year-over-year, so actually showing diesel demand growth in our system. I think some of that heating oil demand has been strong, a little bit colder winter this year, starting to see some drilling activity pick up, which, of course, helps diesel demand. And then, of course, with people spending disposable income ordering things, freight -- on-road freight, trucking and rail has been strong as well. As we move throughout the year, we expect to see some incremental diesel demand coming from ag, as you start to plant crops. And then, moving throughout the year, we also see that as jet demand begins to recover, it will lower diesel yields and help bring supply and demand into balance, which will set diesel up nicely longer-term.
